windows - 是否有类似 pushd 和 popd 的命令可以处理控制台窗口大小、文本颜色和窗口标题？

Question

正是标题所说的。我有一个批处理脚本可以更改控制台的窗口分辨率、标题和文本颜色。当它关闭时，我希望我的脚本将所有这些恢复到用户最初的状态。这怎么可能？

Answer 1

您可以将所有这些数据保存在各种文本文件中，就像这样。

set /p title=Create a Title: 
title %title%
break >"title.txt"
echo %title% >>"title.txt"

这将询问用户他们喜欢的标题名称，并且此标题名称将保存在文本文件中。现在要将其设置为从现在开始的标题，您可以这样做。

if exist "title.txt" (
    set /p title1=<title.txt
    title %title1%
)
set /p title=Create a Title:
title %title% 
break >"title.txt"
echo %title% >>"title.txt"

这将首先测试用户是否在过去指定了一个标题，如果是，那么它将相应地更改标题，如果没有，它将提示用户输入一个标题。

Answer 2

这些存储在几个地方，但主要位于 HKCU\Console 下的注册表中。此外，默认情况下，cmd 标题只是 cmd.exe 的路径，但如果您通过快捷方式打开它，则标题会更改为快捷方式的名称。不幸的是，快捷方式的位置随每个 Windows 版本而变化，并且无法确定命令提示符是如何打开的，因此我们坚持使用默认的默认标题。

将您的其他代码粘贴在标有“您的其他代码”的部分中，或者只写一行call yourscript.bat。
